I read that. However the alternative is to leave the thread in the  
loop. The inconsistency is still there. In addition, the looping  
thread could have some critical data structure locked. In that case  
the JVM (or perhaps one user or one test, etc) could be unusable. I've  
never actually seen that in one of these looping situations. There's  
no really safe alternative other than restarting the JVM, and even  
that could leave the database in an inconsistent state. You pays your  
money and takes your choice.
